VEHICLE LIFTING-JACK.

To all whom it may concern:

Be it known that I, MORLEY P. JACKLINE, a citizen of the United States,residing at Atchison, in the county of Atchison and State of Kansas,have invented certain new and useful Improvements in Vehicle Lifting-Jacks, of which the following is a specification.

This invention relates to vehicle lifting jacks, and belongs moreparticularly to that class of devices which are intended to raise one oranother wheel of a vehicle, for example, an automobile, by means of theoperation of the vehicle itself. This invention comprises a membertermed a shoe in the description, and the shoe is pivotally connectedwith an axle of the vehicle near one of the wheels. Ordinarily, by theaid of certain auxiliary parts, the shoe is held in a raised position,is hoisted up sufficiently to clear all usual road obstructions. When itis necessary to use the shoe for the purpose of lifting a wheel to giveattention to the tire or for any needed act, the shoe is permitted toswing vertically downward until its foot or free end touches the ground,the arrangement being such raised and lowered upon that side of the axlethat is toward the front of the vehicle. The length of the shoe isgreater than the length of when the end of the shoe touches the groundthe shoe is in a inclined .attitude. Now, if the vehicle is moved ordrawn forward the shoe, acting against the ground, by a sort of rollingand lifting action raises the wheel upward for a short distance. l v

The object of this invention is the productipn of a shoe and of theparts concerned in its pivotal support and in its operation, havingspecial construction and arrangement by which it is believed theoperation may be carried out quickly and conveniently, and the part maybe readily and cheaply made in particularly durable shape, the wholebeing always at hand for use at any time.

The construction and arrangement of the parts of this invention areillustrated in the accompanying drawings, of which Figure 1 is a sideview of a portion of the frame and running gear of an automobile withthis invention applied to the frame and axle. In

Fig. 1 the shoe is shown in its raised posi- Specificatlon of LettersPatent.

tion. Fig. 2 represents the wheel of the vehicle, and shows the shoe inits vertical or operating position and the wheel raised.

Fig. 3 is a side view of the shoe, and Fig.

4 is a vertical section thereof on the broken line 4-4 of Fig. 3. Fig. 5is a view showmg the axle of the vehicle in cross-section on the brokenline 55 of Fig. 6, and'showng also one sideof each of the twin clamplngmembers appliedto the axle, and the shoe held thereby in its verticalposition. F g. 6 1s a vlew partly in section on broken line 6 6 of Fig.5, the view being taken in the dlrection of the arrow in Fig. 5, andboth sides or half-collars of each of the clamping members beingillustrated. In F1gs. 3, 4, 5 and 6 the scale of drawing has beenincreased to render the drawing clearer and more easily understood.

Throughout the description and draw double collar, and to further holdthem in place upon'an axle or axle casing there are provided the setscrewsG and 9, best shown in Fig. 6.

Pivotally engaging the clamping members 1s the shoe H, that may or maynot have the handle it. The handle is useful when the shoe is used byitself, as will be hereinafter explained. As the parts are ordinarilyarranged, a connecting rod J is pivotally coupled to the shoe, and therod is also pivotally oined to the lower end of the lever 51' that issupported uplon the frame A. A. second rod K pivota y connects the leverj and the bell-crank lever is, and one leg of the bell-crank isconnected with the rod L which passes upwardly through the footboard aand terminates in a head M. The

head M may if desired be provided with a' thumbscrew m, by which thehead M is releasably secured to the footboard a. When the head M is'thussecured, the shoe H is held inits raised position, as shown in Fig. 1.The parts just explained and described are convenient and desirable forraising,

lowering'and securing the shoe in position but this invention is notrestricted as stated,

to the particular forms and disposition those parts.

As best set out in Figs. 3 and t, the shoe H has at the top a concave,semi-circular flange or head N, and it will be noted that side flangesextend downwardly and join together in a rounded bottom flange. A middleweb n joins all the flanges, and the flanges and web are mostadvantageously made in one piece. By means of the handle h, the shoe IImay be used by itself. It may be placed in a downwardly and forwardlyinclined position beneath the axle O of a buggy, the lower end or flangeof the shoe being against the groundand by moving the a buggy forwardthe axle will be raised into the position shown in Fig. 3. It isbelieved to be well understood that when the shoe is intended for use byitself to raise buggy wheels ,or the like, it must have suitable lengthfor the purpose.

Considering Figs. 5 and 6 it will be seen that the clamping members Eand 6, each comprise two semi-circular ortions connect: ed by the bridgepieces and Q. Each clampin member as customarily made is a single pieceof metal, and consists of the two sides or half-collars and the bridgepiece as shown. Each clamping member has two semi-circular shouldersinteriorly and oppositely placed and formed integrally with the otherparts. The shoulders for the member E are designated by the lettersR andr, and

those for the member 6 by letters S and s.-

The concave head or flange N of the shoe has like curvature and fits theshoulders described. When the parts are assembled upon the axle casingd, the head N of the shoe is placed between the clamping members and inengagement with the inward shoulders of those members. As best set outin Fig. 5, it will be noted that the upper curved ends of the flange orhead N of the shoe H pass between the bridge pieces P and Q and theshoulders. In Fig. 2, the left hand end of the curved head or prong N isshown beneath the bridge piece P, but, it is believed to beclearlydiscernible from Fig. 2 that,

when the shoe II is swung upwardly into its raised position the ends ofthe head N will be under both bridge pieces. By reason of thatconstruction and arrangement, the head N is at no time free fromconnection with illustrated in Fig. 1, the shoev being in its raisedposition. Now, it is desired to raise the wheel G in order that the tireand rim may be removed for repairs. The thumbscrew m is released and theshoe permitted to with its free end upon the ground a little in advanceof the axle D. Now, if the machine be started forward, the shoe willbear upon the ground and be I'Qliiin; ma.. vertical position as shown inFig. 2, and the wheel 0 will be lifted at the same time. In Fig. 5 itwill be noted that one of the pieces, P, is arranged to limit the reatanmovement of the body of the shoe with respect to the axle. Thisarrangement is to prevent the shoe from turning too far rearwardly andletting the wheel down again. After the tire has received the neededattention or other repairs have been completed, a slight rearwardmovement of the frame A. will free the shoe from the weight, andpressure of the foot upon the head M exerted by a person seated in thevehicle, will raise the Having now described this invention, and yexplained the mode of its operation, claim is:
